Table.RemoveLastN

傳回已移除最後 N 個資料列的資料表。

Syntax

Table.RemoveLastN(
    table as table,
    optional countOrCondition as any
) as table

Remarks

傳回資料表，其中不包含資料表 table 的最後 countOrCondition 個資料列。 移除的資料列數目取決於選擇性參數 countOrCondition。

• 如果省略了 countOrCondition，就只移除最後一個資料列。
• 如果 countOrCondition 是數字，就移除該數目的資料列 (從底端開始)。
• 如果 countOrCondition 是條件，就移除符合該條件的資料列，直到資料列不符合條件為止。

Examples

        [CustomerID = 3, Name = "Paul", Phone = "543-7890"],
        [CustomerID = 4, Name = "Ringo", Phone = "232-1550"]
    }),
